# Grinding Media Piece Weight Calculation

Get Price

Apr 29, 2017 If, as previously suggested, the wear varies as the weight of the ball, then R = KW = Kπ/6SD , in which S is the weight of the material from which the balls are made and D is the diameter of the ball in question. This formula shows the rate of wear at any instant

Mar 14, 2017 The container is weighing, when it filled by grinding media as much as possible. Weighing can be done by any measuring instruments: crane scales, stationary scales, etc. It is important that weighing takes by the same measuring instruments and under the same conditions. Bulk density (bulk weight) determined by the formula: = (G1-G) / V (t / m ) Where: G1 – container weight with grinding media (t); G – container weight
